README
hardware/voice/mono - through-hole/README.mdMonophonic Synth Based on the AS3397 Chip: The Voice Board through hole version
The simplest version to assemble and arguably the best starting point. This is a standalone analog voice module that does not require a conductor board to generate sound. Additionaly, the board is large and use trhough-hole component (except for the as3397 chip). It also includes a dedicated MIDI input socket and power circuitry, allowing you to simply connect a MIDI cable and a +12V power supply to get a fully functional monophonic analog synthesizer!

Questions
How big is the AS3397 proto DIP PCB?
It measures 167.6 × 97.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the AS3397 proto DIP use?
142 parts, built around the TL072, LM7805, LM7812 and BS170. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the AS3397 proto DIP KiCad files?
From the PhysicsDptAngers/polyUAnalog repository on GitHub, at the commit this page was made from: the board is hardware/voice/mono - through-hole/AS3397_proto_DIP.kicad_pcb and its schematic hardware/Bus/carte_BUS_1.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the AS3397 proto DIP design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
